department_histories: Data on department histories
In jfjelstul/ecio: The European Commission Internal Organization (ECIO) Database

This dataset includes data on the histories of the current departments of the Commission, including Directorates-General and service departments (1958-2021). There is one observation per historical interval in which the nomenclature of a department is constant. Unlike allocations, intervals can span Commissions. By sorting the dataset by current department, you can see the evolution of each department over time. The dataset indicates the Commissions associated with each interval and the start and end dates of each interval.
